SWITCH STRUCTURE.

Specification of Letters Patent.

Patented April 30, 1907.

Application filed November 3, 1906. Serial No. 841,883.

To all whom, it may concern.-

Be it known that I, Vrc'ron ANGERER, a citizen of the United States,residing at Ridley Park, Pennsylvania, have invented cer- 5 tainImprovements in Switch Structures, of

which the following is a specification.

My invention relates to certain improvements in means to prevent carsstraddling switches.

IO The object of my invention is to construct a switch tongue actuatingmechanism so that its elements can be set in three positions, namely,that the switch tongue will be thrown to and held only in its normalposi- I5 tion at the left of the structure, or thrown to and held in itsnormal position at the right of the structure, or thrown to and held ineither the right or left position; the mechanism be ing so designed thatit will allow the tongue 20 to yield when a car passes over the switchstructure from the heel end of the tongue, but will prevent accidentaldisplacement of the tongue.

Referring to the accompanying drawings:

2 5 Figure 1 is a transverse sectional view through the switch structureand switch box, illustrating my improved mechanism; F ig. 2, is a planview of the switch box with the cover removed; Fig. 3,is a transversesectional view on the line 33, Fig. 1; Fig. 4, is a perspective view ofthe rocker illustrated in Fig. 1 Figs. 5 and 6, are perspective views ofdetails of the invention; Figs. 7, 8 and 9, are views of modificationsof the invention; Figs.

3 5 10 and 11, are diagram views showing the rocker in position so thatthe switch tongue will normally rest against the left side of the switchstructure; Figs. 12 and 13, are views showing therocker in position sothat the switch tongue will normally rest against the right side of thestructure; Figs. 14 and 15, are diagram views illustrating the rocker insuch a position that the switch tongue will normally rest against eitherthe left or right 4 5 of the switch structure.

Referring in the first instance to Fig. 1, A is the switch structurehaving a movable tongue (1. The switch structure in the present instanceconsists of a body portion A made of cast iron or steel and in someinstances may be made of manganese or other hard steel and mounted in arecess in the body portion is a hard metal center piece A forming theright and left hand walls a a of the cavity in. which the switch point(L is piv- 5 5 oted. At one side of the switch structure is a box Bhaving a cover B with a deep flange,

as indicated, which rests on a rib b on the interior of-the box. On eachwall of the box are three sockets c, c, c for the reception of therocker I). This rocker is made as clearly shown in Fig. 4, and has twoside members and a cross bar (l with two sets of hubs d, (Z one of thehubs on one side being longer than the others so that there can be nomistake in putting the rocker in its sockets. E is a rod having aprojecting point e which extends into a cavity in the under side of theswitch tongue (I/ in the present instance, the inner end of this red isscrew threaded and mounted on the screw threaded portion is a head 0which is forked to engage the cross bar (Z of the rocker D. This headcan be adjusted 011 the arm by turning the nuts 0, as clearlyillustratedin Fig. 1. The head is illustrated in Figs. 1 and c, is made in twoparts with one or more spacing washers between them, the parts areclamped together on the rod E by the nuts c and around the cross bar (Zof the rocker, but the head may be made in one piece as in Figs. 7 andS. Hung to the cross bar d between the forked members of the head E is ahook F. This hook is screw threaded at its lower end and mounted on thescrew threaded portion is a nut f having 8 5 knife edge pivots f at eachside. These knife edge pivots rest in a notch 0n the under side of alever G having a hooked inner end 9 which rests under a cross bar Cfirmly secured to the box B. As shown in Figs. 1 go and 2, the free endof the lever G is in the form of a box 9 in which can be placed anysuitable material to be used as a weight to return the parts to theirnormal position.

It will be noticed that when the hubs (Z are 5 in the socket c, asillustrated .in Figs. 1, 10 and 11, the normal position of the switchtongue is at the left hand side, as illustrated in Figs. 1 and 10. henthe hubs (Z are in the sockets 0 as illustrated in Figs. 12 and 13, thenthe normal position of the tongue is at the right hand side. When thehubs d are in the sockets c, as illustrated in Figs. 14 and 15, then thenormal position of the switch tongue is either at the right or left handside of the structure, as it will be noted in these figures the weightedlever is down in either case and the cross bar simply shifts from oneside of the center to the other, whereas in Figs. 10, 11, 12 and 13, thecross bar does not pass the center line through the pivot of the rocker.

It will be seen that all that is necessary to alter the switch is tolift the rocker out of one set of sockets and set it in either of theother sets of sockets. No additional mechanism is added nor is anymechanism omitted.

The rod E can be longitudinally adjusted in its head 6 so as to set theswitch point as desired.

In Fig. 7, I have illustrated a modification in which a coiled spring isused in place of the weighted box 9 of the lever. The lever G in thisinstance is shortened and is forked at its outer end, and passingthrough the forked portion is a rod 9 on which is mounted a spring 9 atelescopic box gf incloses the spring. The rod g has an eye at 1ts lowerend engaging a hook g projecting from the box.

Otherwise the parts are identical with those illustrated in Fig. 1, withthe exception that the block 6 is made in one piece.

In Fig. 8, I have shown a flat spring G3 bearing upon the lever G theflat spring rests in a cavity 1) in the box and a set screw 6 bears uponthe spring so as to place more or less tension upon it, the set screw iscarried by a block b hooked to the side of the box.

In Fig. 9, I have shown an S-hook F in place of the single hookillustrated in Fig. 1, and the shape of the head 6 of the rod E isslightly different from that illustrated in Fig. 1. The S-hook F engagesthe cross bar (1 of the rocker D and is hooked onto a bar 9 on aweighted lever G Thus it will be seen that if it is desired to provide atongue switch in which the tongue is normally in the left hand positionthe rocker is placed in the position illustrated in Fig. 10, themechanism will hold the tongue against accidental displacement and willreturn it to its normal position if moved. If the tongue is to benormally in the right hand position then the rocker is placed in theposition illustrated in Fig. 12. If a switch 18 to be provided in whichthe tongue can be moved from one position into another and held ineither position against accidental displacement then the rocker isplaced in the position illustrated in Fig. 14.

I preferably so construct and arrange the mechanism that the rocker willmove in a vertical arc, but when the springs are used such as shown inFigs. 7 and 8, the mechanism can be arranged horizontally if desired.

I claim 1. The combination of a movable switch tongue, means for holdingthe tongue in its normal position, a rocker connected to the tongue, aseries of bearings for the rocker, ar-
